One thought on “How to get information about your file system in Ubuntu”

Hi there:
A friend of mine tried to help me get my computer up and running after it froze. So, she had a friend of hers come over , and while we were gone he put ubuntu on my computer. I am 67 years old and never heard about ubuntu
and I am not that computer literate. But I did find out that it does not recognize the internet nor the printer . The guy that put it on we can’t find, now i have forgotten my password to get into gnome where I have a document . I am requesting a book or some way to get on the internet because the internet is where I do my research for my church.
